This is the second installment of our lessons on flight. You can read about our first portion (which covers the four forces of flight and kites) in this post.
Hot Air Balloons, Airships, and Parachutes
Next in the human flight story is the hot air balloon. After reading Yasuda’s chapter on hot air balloons, airships, and parachutes, we tried creating our own hot air balloon. We failed, but it was fun and exciting enough to be worth your effort, even if it doesn’t work. Though Yasuda offered one option in her book, ‘Love objected to it because it relied on a hair dryer to work; he argued that it would confuse the matter by including blowing air in the process of causing the balloon to rise. While modern balloonists may use fans to help initially fill their balloons, the blowing air is not the mechanism that causes the balloon to rise. Continue reading
The kids unanimously agreed that they wanted one of their next unit studies to be about flying. As I began typing up all of the activities we’ve been doing, I realized that my post was getting super long, so I’ve once again separated our study into parts. This first part will encompass our study of the four forces of flight and kites. Our projects with hot air balloons, gliders, airplanes, and more will be coming soon.
I thought it would make the most sense to talk about the history of flight in chronological order. Thankfully, I stumbled on Explore Flight! by Anita Yasuda. The book starts with flight in nature–the inspiration for humans who wanted to fly–and ends with rockets. Included are “25 great projects”–though I had issue with a few, particularly the ornithopter project, which was really just a glider with some added feathers.
Of course, I can’t just use one book and leave well enough alone, so I did quite a bit of supplementing and elaborating by using additional materials. Continue reading
